I recently connected a Seagate 400 GB HD to my iMac G5 and it works fine --- except for one small, but very irritating, problem. The computer doesn't recognize the Seagate unless I restart the computer. The external HD icon doesn't appear on the screen when I turn it on, and Disk Utility doesn't show it exists. However, if I restart, the Seagate icon immediately appears, and Disk Utility now knows it exists. What's so annoying, in addition to having to wait for the computer to reboot, is that I have to put things I'm working on back on the Dock every time I restart. Any suggestions?
